Previously, much of the road was called Keflavíkurvegur ([ˈcʰɛplaˌviːkʏrˌvɛːɣʏr̥]) but the name is now given to route 424 that runs from Reykjanesbraut through outer Njarðvík and Keflavík. The current road is mostly dual and controlled-access. In addition to being the main road between Reykjavík and Keflavík Airport, it serves as a major traffic artery in the eastern and southern suburbs of the Capital Region. It runs from the intersection of Miklabraut-Sæbraut-Vesturlandsvegur south towards Hafnarfjörður, where it bends, and continues from there to Keflavík. The road was finished in 1912 and was paved in 1965. 2003 saw the start of construction to upgrade the non-urban part to a four-lane road, being completed by October 2008.^[1]

As a national highway the route includes a large part of Sæbraut [ˈsaiːˌprœyːt], a local road in Reykjavík that begins at the northern end of Reykjanesbraut. Therefore, the stretch of Sæbraut east of Kringlumýrarbraut is marked as number 41.
